Oh, I thought you lost it. Yeah you should just be able to unscrew that top part completely and it will fit right back in the hole, like this. Just unscrew the "11" part off of the "9" and put the "12" back inside of the "9" if that makes any sense.

You can call meAaron.

Well whenever I pull out the trem arm, it just pops back out. You have to unscrew the top piece to get the arm back into it. I have to store it in the case. Or are you actually talking about removing the actual nut from the tremolo?
